Exam 6: Cell Function

Two solutions of different concentrations of glucose are separated by a membrane that allows both glucose and water to pass through. When dynamic equilibrium is reached, there will be:

Gated membrane channels can be opened and closed only by chemical stimuli.

Both temperature and pH change can affect the allosteric site of an enzyme.

The small water channels in the cell membrane are called:

Which is true about the sodium and potassium pump?

Name the three types of vesicle-mediated transport and explain how they are different.

Endocytosis can occur when molecules bind to membrane receptor proteins.

Briefly explain the citric acid cycle. Name the energy molecules produced, and explain how many of each are produced.

Materials can be moved from a low concentration to a high concentration through:

The electron transport system makes ATP by the movement of electrons through the inner mitochondrial membrane.

After phagocytosis occurs, enzymes from which organelle can digest what is in the vesicle?

Protein synthesis is an anabolic pathway for cells.

Match the name of each enzyme with its function or description. -Add or remove phosphate groups

Match each term with its description. -End product of glycolysis

Digestive enzymes belong to which group?

For osmosis to occur, a selectively permeable membrane must be present.

A side effect of exocytosis is the addition of new membrane material to the cell membrane.

Most of the chemical energy released by the citric acid cycle is in the form of ATP.

Red blood cells placed in a hypertonic solution may be destroyed because the blood cells will lyse.

The hydrolyzing enzyme sucrase joins two sucrose molecules together.
